How I Built and Launched a Developer Tool in One Weekend from a Chromebook

I'm not a professional developer. But I had an idea on Friday night and by Sunday I had a live product at troubleshooting.sh. Here's exactly how it happened. The problem I kept running into Every time I hit a cryptic error I'd copy-paste it into ChatGPT and get back something like "make sure your variable is defined." Technically correct. Completely useless. I wanted something that...

CSS calc() function and 100% value

In this example, I create a div element with 100% width. I then compute in two different means the position of the mouse in the div: left-most position should give value 0, while right-most position should give value 1 (ratio of offset to width). I compute in javascript and that works as expected. I also compute with css, but I get a completely different result. There must be something I am missin...

I Stopped Using YouTube for Focus Music and My Pomodoro Sessions Got 10x Better

I run a Pomodoro timer every working day. Not because I read a productivity book. Because I kept losing 25-minute focus blocks to a YouTube ad for meal kits. The ad problem nobody talks about The Pomodoro Technique is simple: 25 minutes of focused work, 5-minute break, repeat. Francesco Cirillo designed it in the late 1980s with a tomato-shaped kitchen timer. No WiFi. No subscription. ...

From Vibecoding to Vibelaunching: Building the ecosystems-cli

12 months ago I set a goal: ship a production-ready CLI for the ecosyste.ms API, in Python. Some commits later, ecosystems-cli is about to land on PyPI. A deliberate attempt to take LLM-assisted development seriously on something larger than a toy. Why bother I follow the AI critics and agree there are real risks in LLM-supported development. But criticism grounded only in theory is th...

Implementing WebMCP on a Recruitment Website

Thinking about what, exactly, the future of a website “looks” like in the agentic era is a challenging proposition. It might be that in most cases, our future viewers/readers/customers can do everything, from their chatbot of preference while never visiting your site. WebMCP is a part of this puzzle. The protocol directs an agent to stop guessing what a button does, and starts calling tools with ...

I built a film camera simulator in a single HTML file here's how

Launched today: faxoffice1987.com — 8 film cameras simulated in Canvas 2D. The constraints I set myself: One HTML file No build step, no dependencies, no npm install Runs offline from a USB drive No backend, no account, no uploads The hard part: per-pixel color science. Each film stock (Tri-X, Portra, Velvia, Neopan Acros) has its own render path. Not a filter on top — a decision at the pix...

Sensitive Data Exposure - The Bug That Looks Like a Feature Working Correctly

The API response came back 200. The data was correct. The test passed. Nobody noticed the response body also contained the user's hashed password, their internal account ID, a debug flag set to true, and a field called admin_notes that was never meant to leave the server. Sensitive Data Exposure does not look like an attack. It looks like a feature working correctly. TL;DR Sensi...

So we run a tech newsletter, and I used to spend my whole Sunday trying to find repos worth writing about. Github trending was useless. it's either huge projects everyone knows already or random stuff that got lucky on HN and then died. so I got annoyed enough to build something. it works way better. but the real lesson was how much junk you have to filter out before the ranking even matters. ...

When should you use canary deployments?

One solution for a tricky or high-risk deployment is to leverage a canary deployment. In a canary deployment, new features are rolled out to a small subset of your customer base with no fanfare. If things go well: hooray! Canary deployments are ideal for times when a deployment might go sideways or the feature might not work as expected. By utilizing a canary release, you have minimized the risk, ...
